PRINTING-MACHINE.

machines of the rotary type wherein an en less web or roll of paper or other material is operated upon.

According to the invention water or spirit- .uous color may be sprayed directly u on the web or sheet in its course through t e machine before the first impressional printing, after such printing, or before and during fol ing, so that thus either a ground or flatting tint or tints may be given to the plain web or sheets or impressed or printed part or parts, as the case may be. y such means various color effects may be procured very conveniently and inexpensively.

In carrying the invention into effect spraying apparatus is used substantially the same as that rovided, as described in the specification iiled on application by me of even date, Serial No. 180,259. Other spraying devices and apparatus may be employed.

The invention is illustrated in the accompanying drawings, in which- Figure 1 shows a diagrammatic elevation of a rotary-printing machine with means incorporated upon it for tinting or coloring the web by direct spra ing upon it of color or ink. Figs. 2 and 3 are etailed end elevation and side elevation, respectively, of the spraying as illustrated in Fig. 1,

uired in the tinting or coloring of the web. Figs. 4 and 5 show detailed end elevation and side elevation, respectively, of means for giving a lateral movement to the spraying devices employed, as illustrated in the arrangement illustrated in Fig. 1. Figs. 2 and 4 are diagrammatic views showing the fundamental efiects that are produced, respectively, by cutting off the spray, as illustrated in Figs. 2 and 3, and by the lateral movement of the spraying devices, as illustrated in Figs. 4 and 5.

It will be understood that for multicolorprinting a number of spraying devices may e arranged one above the other for spraying color direct upon the web and so as to render Specification of Letters Patent. Application fil fl November 7,1903. Serial No. 180,268.

to associate or blend two colors iproduce a particular secondary ue or tint, if required, while the it possible together to or resultant means employed for adjustment may be so arranged as to render the respective parts easy of adjustment to vary the tint or to intermittently stop the spraying, as may be required in the working of the machine. Similarly the spraying devices may be arran ed in horizontal series or the may be provi ed so as to be ca abl e of a justment horizontally or vertica ly upon a pivotal center.

Means provided for spraying color upon the web are illustrated in Figs. 1 and 5 of the accompanying drawings. 10 of a shape and of a number corresponding to the spraying devices It employed in anyparticular case may be provided in such re ation thereto as to be capable of being intermittently brought into position to intercept the spray. The reciprocating or-vibrating movement of these shields may be effected automatically from any continuously-rotating shaft on the press, such as 11, and by such means connecting rods or links 12 and levers 13, which may be so provided as to move the shield or shields 10 in front of the spraying device or devices it to intercept the spray as determined according to the particular work to be done. Such an arrangement is particularly serviceable in spraying color direct onto the web where a articular tint or tints may be deposited on tiie Web in any particular part of a page or on any particular page or pages, as may be required. The movement of the shield or shields 10 may be effected quickly, so that the spray may be cut off instantly by such means as a cam 14, Fig. 4, so that the cessation of spray shall only be momentary. The shields 10 are advantageously mounted upon a rod 15, extending across the machine, and are made in sections of standard width by which the total effective width of the shields may be reduced or increased, as required in partic ular cases. The respective sections constituting the shield may advantageously be provide with their circumference concentric with. the rod upon which they are mounted, and they may be carried by means of a ledge 17, reaching across the machine, which ledge is integral with an arm 18, capable of sliding upon or ofof the spraying devices, with their peripheral A shield or shields 5 duced,u on the web.

As illustrated in Figs. 4'and 5, a lateral movement may be communicated to the sprayer-s h or to the rod y', upon which they are mounted, by means the same as illustrated in Figs. to 12 of the drawings ac- 2o companying the companion application of even date, which permits of the cam 4 being adjusted into any articular angular position as required to give the lateral movement to the spraying devices It at the pro er tirge. ape emg employed to give movements according to the particular effects that are to be roduced, or instead the toothed gear-whee 19 may be slotted and may carry the extremity ositive movement may be given to the rod yand the spraying devices 72 direct from the gear-wheel 19. A number of spraying devices in horizontal or vertical series may be provided before, or between the printing-couples, and by-their means water or spirituous color may be sprayed upon the web 20 according to any particu ar ground that may be required. For example, when it is required to employ one side of the web as the cover or outside sheet ofa rinted and folded product a set of spra ing devices will be provided to continuous y apply color on the web at that part, or if only one side of the folded cover-sheet re uires tinting a shield may be employed to ntercept the spray periodically, so as to only tint the part of the Web required. Fig. 2 shows the effect of thus intercepting the spray completel across the web at equal intervals of liy such mechanism as that illustrated in Figs. 2 and 3, or, again, the edge .of the web employed as the cover or the whole web itself may be tinted with various colors to produce a wave efl'ect, Fig. 4, in which case 5 5 a number of spraying devices h, corresponding to the number of colors used, may e arranged in horizontal series over that part of the .web to which a lateral movement may be communicated by such mechanism as that at a rate corresponding to the speed of the web, or, again, t e web or part of the web may be completely covered with one tint by one set of sprayers, while a part of the web may be covered with another tint to cover thefirst, so that advertisements or other matter might be attractively and prominently brought out.

It will thus be understood that innumerable effects can be produced by the provision of sprayers for the lateral movement, as herein before described, and by the employment of shields for the periodic interception of the spray either in a circular or in a lateral movement of the shields.
